Just found these on the RV Business website. FYI
1 (2004) Newmar Essex diesel pusher motorhome built on a Freightliner chassis and equipped with Bendix SR-7 spring brake modulating valves. The internal rubber check valve may leak causing a delay in the application of the spring brakes to park the vehicle after the operator pulls the dash valve button.
274 (2005) Newmar Kountry Star diesel pusher, Northern Star diesel pusher, and (2006) Ventana diesel pusher motorhomes built on Freightliner chassis. Specific inline power steering filters may become plugged, resulting in hose separation from the filter or steering gear fitting.
148 (2008-2009) Newmar Ventana diesel pusher motorhomes. After some period of use and due to the unshielded proximity of the primary engine exhaust system, thermal breakdown of the polyethylene moisture barrier may occur and could result in auto-ignition and combustion.
